As a ground source heat pump, the Vitocal 300-G draws thermal energy from highly efficient heat sources. For this, a geothermal probe, an ice store system or a geothermal collector is installed on the property. In all these cases, the heat pump covers the entire energy demand, even on colder days.
As an alternative, depending on the location of the house, it may also be possible to utilise the thermal energy contained in the groundwater. In this case, the Vitocal 300-G is simply configured for operation as a water/water heat pump. It can be used for new build and modernisation in detached houses and apartment buildings.
The German EHPA quality seal commission certifies that the Viessmann Vitocal 300-G heat pump meets the requirements of the EHPA quality seal regulations.
Clear, comfortable, intelligent: The Vitotronic offers perfect functions for fast and exact control of every heating system.
Control Vitotronic 200 - Can also be operated using an app via a smartphone at any time.
The Vitoconnect 100 interface is required for operation via the app. Retrofitting earlier heat pumps of the Vitocal series (from year of construction 2010) is possible at any time.
The ViCare app enables system users to control their heating system via smartphone. The operating status can be viewed at any time and the contractor whose details have been stored in the app can be contacted quickly and easily if a fault occurs.
"The whole is greater than the sum of its parts". Following this philosophy, Viessmann supplies more than high quality, reliable and effective heating components. In fact, all products are part of a matching total concept, where all components complement one another. After all, only perfect interaction between all system components can draw out the maximum potential of our innovative leading technology.
Viessmann system technology incorporates everything you need for a reliable and economical heating system: From the Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for the highest DHW convenience, right up to high grade solar thermal systems for cost effective central heating backup.
The powerful Compliant scroll compressor fitted in the Vitocal 300-G heat pump is outstanding on account of its high operational safety, reliability and especially quiet operation. Essentially, this is due to the double sound insulation measures that include anti-vibration mounts to prevent structure-borne noise and insulation of the casing against airborne noise. At the same time, the compressor guarantees the highest coefficient of performance (COP up to 5.0) and flow temperatures up to 65°C.
The Refrigerant Cycle Diagnostic (RCD) system constantly monitors the refrigerant circuit in the Vitocal 300-G and, in conjunction with the electronic expansion valve, ensures the highest efficiency at any operating point, which results in high seasonal performance factors.
For residential buildings with a higher heat demand, the two-stage Vitocal 300-G based on the master/slave principle is the right choice. It can also be configured for the ground or groundwater as the heat source. For this purpose, two heat pumps are linked together. This delivers the high heating output required and increases the operational reliability of the entire system. The modular layout, with separate compressor circuits, also ensures particularly high levels of efficiency in partial load operation, and enables the simultaneous operation of central and DHW heating.
With five output stages as a master or master/slave version, various combinations can be realised and matched to the required heat demand. Because of this flexibility, systems can be configured so that runtimes match demand, thus ensuring economical operation. The master module regulates the slave module. Furthermore, the entire system can be equipped with high efficiency pumps.
The Vitoconnect 100 is a WiFi interface to establishes the connection allowing you to remotely operate your heating system by app, as well as supporting remote maintenance via Vitoguide.
With the new ViCare app, operating your heating system has become even easier and more intuitive. You can adjust heating times to suit your individual requirements using the integral wizard and see cost savings displayed instantly.
